ABSTRACT

Disclosed is a method for reinforcing a block masonry wall of blocks by use of a fixture, fixture holder, and deformed steel wire. The fixture holder has a hollow pipe shape and includes six blade receptacles protruding outward from a periphery thereof by a predetermined distance. The blade receptacles are spirally formed in a longitudinal direction of the fixture holder by a predetermined pitch. The deformed steel wire has an approximately regular-polygonal longitudinal direction thereof by a constant pitch. The deformed steel wire includes an intersectional connecting portion and/or beam connection loop. A block used in the reinforcing method includes a center hole and a side surface groove, and further includes first and second side holes at opposite sides of the center hole. The side surface groove is formed only at one side surface or either side surface of the block. All the holes have a rounded rectangular shape. The masonry wall reinforcing method includes the steps of: connecting a horizontally extending basic deformed steel wire to a vertically extending intersectional connection type deformed steel wire and covering them with mortar; and connecting a fixture holder, which is oriented toward an inner wall, to the vertically extending intersectional connection type deformed steel wire and covering them with mortar. A beam block reinforcing method includes the steps of: laying a row of beam blocks such that holes of the beam blocks horizontally communicate with one another, and penetrating a first deformed steel wire through the holes of the beam blocks; and horizontally disposing a second deformed steel wire on upper surfaces of the beam blocks.

TECHNICAL FIELD

The present invention relates to a fixture holder, deformed steel wire,and block for use in a method for reinforcing a masonry wall, and moreparticularly, to a masonry wall reinforcing method wherein fixtureholders, each being coupled with a fixture press-fitted into an innerwall, are connected to one another by use of vertically and horizontallyextending deformed steel wires.

BACKGROUND ART

A masonry wall is constructed by a constructional work for building awall by piling up stones, bricks, concrete blocks, etc. Generally, apurely masonry structure is referred to a brick structure, stonestructure, and concrete block structure, which use no reinforcement.Such a masonry structure generally has a good durability and inparticular, the stone structure has been used for a long time. In theWestern Europe, etc. having a rare occurrence of earthquake, a varietyof masonry works have been employed without a drawback in structuralstrength. In relation with the masonry works, moreover, a long time agothere were developed various decorative designs including arches anddomes. Even in these days, for example, the block structure is widelyused.

The block structure is built not by simply piling up blocks, but bylaying blocks at the outer surface of an inner wall that is made ofconcrete, etc. Therefore, it is very important to achieve a sufficientcoupling force between the inner wall and the blocks. If there occurs adeterioration in the coupling force between the inner wall and theblocks, it may cause a collapse of the laid blocks by an earthquake,wind pressure, or other external shocks.

Accordingly, to prevent various unexpected accidents caused by, forexample, the collapse of blocks, there exists a serious need for astrong coupling between the laid blocks and the inner wall. As asolution to reinforce the coupling of blocks, conventionally, it hasbeen proposed that a fixture, which consists of a core and spiralblades, is fitted into an inner wall, for achieving an increase in thecoupling force between the blocks and the inner wall.

However, the above described solution has a problem in that a greatnumber of separate elements should be used for fixing the fixture, whichwas fitted into the inner wall, to the blocks. This results in aninconvenience in the use of the fixture.

DISCLOSURE [Technical Problem]

Therefore, the present invention has been made in view of the aboveproblems, and it is an object of the present invention to provide amethod for reinforcing a masonry wall wherein fixture holders, eachbeing coupled with a fixture press-fitted into an inner wall, areconnected to one another by use of vertically and horizontally extendingdeformed steel wires, and a fixture holder, deformed steel wire, andblock for use in the masonry wall reinforcing method.

[Technical Solution]

In accordance with an aspect of the present invention, the above andother objects can be accomplished by the provision of a method forreinforcing a masonry wall comprising: connecting a horizontallyextending basic steel wire to a vertically extending intersectionalconnection type deformed steel wire and covering them with mortar;connecting a fixture holder, which is oriented toward an inner wall, tothe vertically extending intersectional connection type deformed steelwire and covering them with mortar; laying blocks; and connecting afixture to the fixture holder by press-fitting the fixture into theinner wall through the fixture holder oriented toward the inner wall.With this method, the fixture holder can be connected to anotherdeformed steel wire by use of the intersectional connection typedeformed steel wire without requiring separate elements, therebyenabling the masonry wall to be firmly supported in vertical andhorizontal directions thereof.

An end of the vertically extending intersectional connection typedeformed steel wire or the horizontally extending deformed steel wire,which is located near the ground, ceiling, or lateral wall surface of abuilding, may be longitudinally connected and fixed, by use of thefixture holder, to the fixture that is press-fitted into the ground,ceiling or lateral wall surface. This has the effect of allowing thedeformed steel wire, which extends in a horizontal or vertical directionof a building, to be more firmly fixed to the ground, ceiling, orlateral wall surface.

The intersectional connection type deformed steel wire may include oneor two intersectional connecting portions. With the use of theintersectional connecting portion, the fixture holder or anotherdeformed steel wire can be simply connected perpendicular to thedeformed steel wire, resulting in a convenience in connecting operation.

Here, each intersectional connecting portion may be formed by circularlybending a portion of the deformed steel wire in a lateral direction suchthat the fixture holder or deformed steel wire is inserted into theintersectional connecting portion. This simplifies the fabrication ofthe intersectional connection type deformed steel wire, and achieves aconvenience in the implementation of the reinforcing method.

When the intersectional connection type deformed steel wire includesfirst and second intersectional connecting portions, the first andsecond intersectional connecting portions are disposed in differentplanes perpendicular to each other and are spaced apart from each otherby a distance equal to the height of a single block. Accordingly, thefixture holder and another deformed steel wire can be connectedperpendicular to the single deformed steel wire while being connectedperpendicular to each other. Also, as a result of separating bothconnecting portions for the fixture holder and the deformed steel wirefrom each other, the overall construction can be simplified.

Preferably, an entrance of the intersectional connecting portion has awidth larger than a thickness of the deformed steel wire and smallerthan a thickness of the fixture holder.

To connect the fixture holder to the intersectional connecting portionof the intersectional connection type deformed steel wire, afterinserting the fixture holder into the intersectional connecting portion,an anchoring fixture holder is fitted around an either end of thefixture holder, the anchoring fixture holder having the same pitch asthe fixture holder, but having a larger diameter and a shorter lengththan the fixture holder. Thereby, the anchoring fixture holderinterferes with the intersectional connecting portion, therebypreventing the fixture holder from being separated from theintersectional connecting portion.

Each deformed steel wire has an approximately regular-polygonal crosssection, and is spirally twisted in a longitudinal direction thereof bya constant pitch. The fixture holder has an elongated hollow pipe shape,and includes six blade receptacles protruding outward from a peripheryof the fixture holder by a predetermined distance, the blade receptaclesbeing spirally formed in a longitudinal direction of the fixture holderby a predetermined pitch. The fixture holder connects two deformed steelwires to each other in a longitudinal direction of the steel wires viaboth ends thereof.

Each of the blocks may include a center hole and a side surface groove,and the center hole has substantially the same shape as a shape definedby two facing side surface grooves spaced apart from each other by adistance equal to the width of a masonry joint. Upon the laying ofblocks, the vertically extending deformed steel wire may be penetratedthrough the center hole of a block and the space defined by the twofacing side surface grooves of an underlying block in turn. Preferably,the center hole and the space defined by the two facing side surfacegrooves have a rounded rectangular shape, in the view of the provisionof a sufficient work space and a high adherence force of mortar.

Each of the blocks may include a single side surface groove formed onlyat one side surface thereof or a pair of side surface grooves formed atboth side surfaces thereof. The block may further include a first sidehole and a second side hole formed, respectively, at opposite sides ofthe center hole, and the first and second side holes have a roundedrectangular shape suitable to increase the adherence of mortar.

In accordance with another aspect of the present invention, there isprovided a method for reinforcing beam blocks arranged on an upper endof a window, for the reinforcement of a masonry wall, comprising: layinga row of beam blocks such that holes of the beam blocks horizontallycommunicate with one another, and penetrating a first deformed steelwire through the holes of the beam blocks; horizontally disposing asecond deformed steel wire on upper surfaces of the beam blocks;connecting the first and second steel wires to each other and coveringthem with mortar; and laying blocks on the row of beam blocks. With thismethod, the reinforcement of beam blocks can be accomplished by use ofelements used in the reinforcement of a masonry wall.

In the case of reinforcing beam blocks of an existing building, theabove method may further comprising: prior to laying the row of beamblocks, removing a row of beam blocks arranged on the upper end of thewindow and a plurality of rows of blocks laid on the row of beam blocks,and supporting the remaining blocks by use of a temporary support.

The first and second deformed steel wires may be connected to each otherby use of a beam connection loop type deformed steel wire, whichincludes a beam connection loop formed at a lower end thereof and anintersectional connecting portion spaced apart from the beam connectionloop by a predetermined distance, or by use of a beam supporting typedeformed steel wire which includes a beam connection loop formed at alower end thereof and an intersectional connecting portion formed at anupper end thereof and spaced apart from the beam connection loop by apredetermined distance. With this connection, the load of beam blockscan be sufficiently supported.

The beam connection loop may be formed by circularly bending the lowerend of the deformed steel wire such that the deformed steel wire isinserted into the beam connection loop, an entrance of the beamconnection loop being opened in an approximately upper lateral region,and the intersectional connecting portion may be formed by circularlybending a portion of the deformed steel wire in a lateral direction suchthat a fixture holder or deformed steel wire is inserted into theintersectional connecting portion, for the sake of simplifying thereinforcement of beam blocks.

After completing the reinforcement of beam blocks, the above method mayfurther comprising: connecting the second deformed steel wirehorizontally disposed on the upper surfaces of the beam blocks to avertically extending intersectional connection type deformed steel wire,and covering them with mortar, or connecting a horizontally extendingbasic deformed steel wire or a fixture holder oriented toward an innerwall, except for the second deformed steel wire horizontally disposed onthe upper surfaces of the beam blocks, to the beam connection loop typedeformed steel wire or an intersectional connection type deformed steelwire connected to an upper end of the beam connection loop type deformedsteel wire. In this way, the reinforcement of beam blocks can beaccomplished simultaneously with the reinforcement of the overallmasonry wall.

BEST MODE

Now, an embodiment of a method for reinforcing a masonry wall inaccordance with the present invention will be described in detail withreference to the accompanying drawings.

FIG. 1A is a configuration view illustrating an embodiment of a fixture1 for use in the masonry wall reinforcing method in accordance with thepresent invention, and FIG. 1B is a sectional view of the fixture 1.

The fixture 1 is made of a metal material having a high strength and acorrosion resistance against moisture, etc. The fixture 1 includes acore 11, and a plurality of blades 12 protruding outward from aperiphery of the core 11 by a constant distance. The blades 12 arespirally formed around the core 11 by a predetermined pitch P in alongitudinal direction of the fixture 1. Although there is no limit inthe number of the blades 12, in an advantageous embodiment as shown inFIG. 1B, the fixture 1 includes three blades, to satisfy bothrequirements of high strength and simple configuration.

FIG. 2A is a configuration view illustrating a fixture holder 2 for usewith the fixture 1 of FIGS. 1A and 1B, and FIG. 2B is a sectional viewof the fixture holder 2.

The fixture holder 2 is made of a moisture-resistance metal material,such as stainless steel, aluminum, brass, etc., a plastic material, orthe like. The fixture holder 2 has a hollow cylindrical shape, and isformed with a plurality of blade receptacles 22 protruding outwardlyfrom a periphery thereof by a constant distance. The blade receptacles22 are spirally formed by a predetermined pitch P in a longitudinaldirection of the fixture holder 2. Here, the pitch P between the blades12 of the fixture 1 coincides with the pitch P between the bladereceptacles 22 of the fixture holder 2. If the fixture holder 2 includessix blade receptacles 22 as shown in FIG. 2B, the fixture holder 2 canbe coupled with a fixture having two or three blades, or a deformedsteel wire having a regular-triangular cross section orregular-hexagonal cross section which will be described hereinafter.

FIG. 2C is a perspective view illustrating an anchoring fixture holder2′, which is configured so as to be fitted around an outer periphery ofthe fixture holder 2. FIG. 2D is a perspective view illustrating twoanchoring fixture holders 2′ fitted around the outer periphery of thefixture holder 2. FIG. 2E is a sectional view of the anchoring fixingholder 2′ fitted around the outer periphery of the fixture holder 2.

The anchoring fixture holder 2′ has the same pitch as that of thefixture holder 2, but has a smaller length and a larger diameter thanthose of the fixture holder 2, so as to be fitted around the outerperiphery of the fixture holder 2. In the course that the fixture holder2 is coupled into an intersectional connecting portion of a deformedsteel wire that will be described hereinafter, the anchoring fixtureholder 2′ serves to anchor the fixture holder 2 to the intersectionalconnecting portion, to thereby prevent separation of the fixture holder2.

FIG. 3A is a configuration view illustrating a deformed steel wire 5 foruse with the fixture holder 2 of FIGS. 2A to 2E, and FIGS. 3B and 3C aresectional views of the deformed steel wire 5. FIGS. 4A to 4D are viewsillustrating different deformed configurations of the deformed steelwire 5 of FIGS. 3A to 3C.

The deformed steel wire 5, used in the reinforcing method of the presentinvention, is formed by spirally twisting a deformed steel wire, havingan approximately regular-triangular, regular-tetragonal (not shown),regular-pentagonal (not shown), or regular-hexagonal cross section, by apredetermined pitch P. The pitch P of the deformed steel wire 5coincides with the pitch P of the fixture 1 and the pitch P of thefixture holder 2 (See FIGS. 1A and 2A).

Specifically, FIG. 3A illustrates the configuration of the basicdeformed steel wire 5, and FIGS. 4A to 4D illustrate differentconfigurations of the deformed steel wire 5. More specifically, FIG. 4Aillustrates an intersectional connection type deformed steel wire 5′,FIG. 4B illustrates a beam connection loop type deformed steel wire 5″,FIG. 4C illustrates a beam supporting type deformed steel wire 5″′, andFIG. 4D illustrates a beam connection loop and intersectional connectionmixed type deformed steel wire 5″″.

Although the shown intersectional connection type deformed steel wire 5′has two intersectional connecting portions 51 a and 51 b, theintersectional connection type deformed steel wire 5′ may have only oneintersectional connecting portion. In this case, by connecting the twodeformed steel wires, each having only one intersectional connectingportion, to each other by use of the fixture holder 2, it is possible toachieve the same effect as the deformed steel wire 5′ of FIG. 4A. Suchan intersectional connecting portion 51 is obtained by circularlybending a portion of the deformed steel wire in a lateral direction suchthat the fixture holder 2 or another basic deformed steel wire 5 can beinserted into the intersectional connecting portion 51. Advantageously,in the view of a convenience in assembling and a rigidness in structure,an entrance of the intersectional connecting portion 51 has a widthsmaller than a width of the fixture holder 2, but larger than a width ofthe basic deformed steel wire 5.

The intersectional connecting portions 51 a and 51 b are arrangedperpendicular to each other, and are spaced apart from each other by adistance equal to the height of a single block. With this arrangement,the intersectional connecting portions 51 a and 51 b can be positionedon different successive rows of blocks, resulting in a simplifiedconfiguration and assembling operation of the deformed steel wire 5′ andblocks. It will be appreciated that the distance between theintersectional connecting portions 51 a and 51 b is not essentiallylimited to the height of the single block. Furthermore, as describedabove, even when the intersectional connection type deformed steel wirehas only one intersectional connecting portion, it is possible toachieve the same effect as the deformed steel wire 5′ of FIG. 4A bylongitudinally connecting the two deformed steel wires each having onlyone intersectional connecting portion by means of the fixture holder 2.

The beam connection loop type deformed steel wire 5″ shown in FIG. 4Bhas a beam connection loop 52 formed at a lower end thereof and anintersectional connecting portion 51 spaced apart from the beamconnection loop 52 by a predetermined distance. The beam connection loop52 is obtained by circularly bending the lower end of the deformed steelwire 5″ such that another steel wire can be inserted into the beamconnection loop 52. An entrance of the beam connection loop 52 is openedin an approximately upper lateral region. Although the deformed steelwire 5″ shown in FIG. 4B has only one intersectional connecting portion51, the present invention is not limited thereto. In an alternativeembodiment, similar to FIG. 4A, the deformed steel wire 5″ may have twointersectional connecting portions, so as to be directly used in thereinforcement of a masonry wall. In a further alternative embodiment,the deformed steel wire 5″ may have only the beam connection loopwithout the intersectional connecting portion. In the latter embodiment,by connecting an upper end of the deformed steel wire 5″ to theintersectional connection type deformed steel wire 5′ by means of thefixture holder 2, it is possible to achieve the same effect as that ofthe beam connection loop type deformed steel wire 5″ shown in FIG. 4B.Moreover, although the intersectional connecting portion 51 and the beamconnection loop 52 of the deformed steel wire 5″ shown in FIG. 4B arearranged in the same vertical plane as each other such that differenttwo parallel steel wires can be connected to the deformed steel wire 5″,the intersectional connecting portion 51 and the beam connection loop 52may be arranged in different planes perpendicular to each other suchthat the fixture holder 2 oriented toward an inner wall can be coupledinto the intersectional connecting portion 51. Referring to FIG. 4D, thedeformed steel wire 5″″ may have the beam connection loop 52, and threeintersectional connecting portions 51 a, 51 b and 51 c, which arearranged above the beam connection loop 52 and spaced apart from oneanother by a distance equal to the height of a single block. Thedeformed steel wire 5″″ can be connected directly to the fixture holder2 or another deformed steel wire, in addition to being used for thereinforcement of beam blocks.

FIG. 4C illustrates the beam supporting type deformed steel wire 5′″,which the intersectional connecting portion 51 formed at an upper endthereof and the beam connection loop 52 formed at a lower end thereof.As compared to the beam connection loop type deformed steel wire 5″shown in FIG. 4B, the deformed steel wire 5′″ has no portion extendingupward from the intersectional connecting portion 51. Here, a distancebetween the intersectional connecting portion 51 and the beam connectionloop 52 is equal to that of the beam connection loop type deformed steelwire 5″ shown in FIG. 4B. In consideration of the fact that deformedsteel wires for supporting beam blocks have to be more densely arrangedthan those used for supporting the remaining portion of a masonry wall,the deformed steel wire 5′″ has a simplified configuration suitable onlyfor supporting beam blocks, regardless of the reinforcement purpose of amasonry wall.

FIG. 5A is an exemplary view illustrating the longitudinal coupling ofthe fixture 1 of FIGS. 1A and 1B by use of the fixture holder 2 of FIGS.2A to 2E, and FIG. 5B is a sectional view illustrating the couplingrelationship of the fixture 1 and the fixture holder 2.

As shown in FIG. 5A, the fixture holder 2 and the fixture 1 have thesame pitch as each other. Thus, the fixture holder 2 and the fixture 1can be longitudinally coupled to each other via their relative spiralrotations. In this case, the fixture 1 can be fitted into the fixtureholder 2 through either end of the fixture holder 2. Consequently, thefixture holder 2 can be used to connect the two fixtures 1 to eachother.

Referring to FIG. 5B, the fixture holder 2, which is formed with sixblade receptacles 22, may be coupled with the fixture 1 having threeblades 12 (FIG. 6B), or may be coupled with a fixture having two blades.Each blade 12 of the fixture 1 is configured such that it can beinserted into an associated one of the blade receptacles 22 of thefixture holder 2 while keeping a slight gap G therebetween. Consideringthe geometrical shape of the blade 12 in more detail, a distance fromthe center of the fixture 1 to an edge of the blade 12 is longer than adistance from the center of the fixture holder 2 to an inwardlyprotruded portion 21 of the fixture holder 2. With this geometricalshape, the inwardly protruded portion 21 of the fixture holder 2interferes with the blade 12 of the fixture 1, thereby allowing thefixture 1 to be caught fixedly inside the fixture holder 2. Once thefixture holder 2 is installed into a masonry wall, the outer peripheryof the fixture holder 2 is surrounded by mortar. Therefore, the fixtureholder 2 has no risk of deformation even if it is compressed bymovements of the fixture 1, and consequently, can more strongly supportthe fixture 1.

In the present invention, the fixture 1 and the fixture holder 2 areconfigured such that the blades 12 and the blade receptacles 22 arespirally formed in their longitudinal direction. Therefore, by simplyrotating the fixture 1 and the fixture holder 2 relative to each othersimilar to a screw fastening manner, the coupling of the fixture 1 andthe fixture holder 2 can be accomplished in a very simplified manner.Moreover, to impart a great flexural rigidity to the fixture 1 and thefixture holder 2, it is advantageous that the cross sectional shapes ofthe blades 12 and the blade receptacles 22 are determined to achieve agreat modulus of section.

As described above, there exists the predetermined gap G between eachblade 12 and the associated blade receptacle 22 in a state wherein thefixture 1 and the fixture holder 2 are coupled to each other. Therefore,when the fixture 1 and the fixture holder 2 are used for thereinforcement of a building, the gap G can absorb a vibration generatedin the building to some extent and also, can deal with an unwantedthermal expansion of materials caused by, for example, a temperaturevariation. Moreover, a spacing S between the core 11 of the fixture 1and the inwardly protruded portion 21 of the fixture holder 2 serves asa moisture or air vent, thereby eliminating the problem of corrosion bystanding water, etc. In addition to the spacing C, the inner volume ofeach blade receptacle 22 remained after receiving the blade 12 can actto increase the cross sectional area of the moisture or air vent. Inparticular, the increased number of curves can allow the blades 12 ofthe fixture 1 to be smoothly guided and inserted into the bladereceptacles 22 of the fixture holder 2 even if the orientation of thefixture 1 is not accurately set to that of the fixture holder 2,resulting in a convenience in use.

FIG. 6A illustrates the longitudinal direction of the deformed steelwire 5 of FIGS. 3A to 3C by use of the fixture holder 2 of FIGS. 2A to2E, and FIGS. 6B and 6C are sectional views illustrating the couplingrelationship of the deformed steel wire 5 and the fixture holder 2. FIG.7 illustrates the longitudinal coupling of the fixture 1 of FIGS. 1A and1B and the deformed steel wire 5 of FIGS. 3A to 3C by use of the fixtureholder 2 of FIGS. 2A to 2E.

Since the pitch of the deformed steel wire 5 coincides with the pitch ofthe fixture holder 2, similar to the longitudinal coupling of thefixture 1 and the fixture holder 2, the deformed steel wire 5 and thefixture holder 2 can be longitudinally connected to each other as shownin FIG. 6A.

In the case where the fixture holder 2 has six blade receptacles 2, asshown in FIGS. 6B and 6C, the fixture holder 2 can be coupled with thedeformed steel wire 5 having a regular-hexagonal cross section as wellas the deformed steel wire 5 having a regular-triangular cross section.

Considering the geometrical shape of the deformed steel wire 5, adistance from the center of the deformed steel wire 5 to a vertex pointof the cross section of the deformed steel wire 5 is longer than adistance from the center of the fixture holder 2 to the inwardlyprotruded portion 21. Therefore, the inwardly protruded portion 21 ofthe fixture holder 2 interferes with the vertex point of the crosssection of the deformed steel wire 5, thereby allowing the deformedsteel wire 5 to be secured inside the fixture holder 2. Once the fixtureholder 2 is installed into a masonry wall, the outer periphery of thefixture holder 2 is surrounded by mortar. Therefore, the fixture holder2 has no risk of deformation even if it is compressed by movements ofthe deformed steel wire 5, and consequently, can more strongly supportthe steel deformed wire 5.

In the present invention, both the deformed steel wire 5 and the fixtureholder 2 are spirally twisted in a longitudinal direction thereof.Therefore, by simply rotating the deformed steel wire 5 and the fixtureholder 2 relative to each other similar to a screw fastening manner, thecoupling of the deformed steel wire 5 and the fixture holder 2 can beaccomplished in a very simplified manner.

Also, there exists a predetermined gap between the deformed steel wire 5and the fixture holder 2 in a state wherein the deformed steel wire 5and the fixture holder 2 are coupled to each other. Therefore, when thedeformed steel wire 5 and the fixture holder 2 are used for thereinforcement of a building, the gap can absorb a vibration generated inthe building to some extent, and also can deal with an unwanted thermalexpansion of materials, etc. caused by a temperature variation, etc.

Meanwhile, in the case where the pitches of the above mentioned threeelements, i.e. the fixture, fixture holder, and deformed steel wire,coincide with one another, as shown in FIG. 7, the fixture 1 and thedeformed steel wire 5 can be longitudinally coupled to each other by useof the fixture holder 2. Accordingly, the vertically or horizontallyextending deformed steel wire 5 can be fixed to the wall or ground of abuilding. For example, if the deformed steel wire 5 is connected to thefixture 1, which was vertically press fitted into the ground, by use ofthe fixture holder 2, the deformed steel wire 5, which extends in avertical direction of the building, can be firmly connected to andsupported by the ground. More specifically, an end of the deformed steelwire, which extends in a vertical direction of the building, is locatednear the ground or ceiling of the building, and thus, can be connectedand fixed to the fixture that was press-fitted into the ground orceiling by use of the fixture holder. Similarly, an end of the deformedsteel wire, which extends in a horizontal direction of the building, islocated near the lateral wall of the building, and thus, can beconnected and fixed to the fixture that was press-fitted into thelateral wall by use of the fixture holder.

However, if it is actually unnecessary to longitudinally connect thefixture 1 and the deformed steel wire 5 to each other, there is no needfor coinciding the pitches of the above three elements with one another.In this case, on the basis of the fact that whether the fixture holder 2will be coupled to the fixture 1 or the deformed steel wire 5, thereexists only a requirement that the pitch of the fixture holder 2 has tocoincide with the pitch of the fixture 1 or the pitch of the deformedsteel wire 5.

FIG. 8 is a view illustrating the fixture press-fitted into an innerwall and the fixture holder connected to a rear end of the fixture,which are connected perpendicular to the deformed steel wire.

The fixture holder 2, which is coupled to the fixture 1 press-fittedinto an inner wall C such as a concrete wall, is connected perpendicularto the intersectional connection type deformed steel wire 5′ via thefirst intersectional connecting portion 51 a. In turn, the basicdeformed steel wire 5 is connected perpendicular to the deformed steelwire 5′ via the second intersectional connecting portion 51 b that islocated below the first intersectional connecting portion 51 a by adistance equal to the height of a single block. Consequently, theadditional steel wire 5 can be also connected perpendicular to thefixture holder 2. Here, an outer diameter of the fixture holder 2substantially coincides with an inner diameter of the intersectionalconnecting portion 51 including the first intersectional connectingportion 51 a, and a width of the entrance of the first intersectionalconnecting portion 51 a is smaller than the outer diameter of thefixture holder 2. Accordingly, the fixture holder 2 cannot be fittedthrough the entrance of the intersectional connecting portion 51, but isallowed to be fitted only through an inner periphery of theintersectional connecting portion 51. Although not shown in FIG. 8, ifthe anchoring fixture holder 2′ is fitted around the fixture holder 2from either side of the fixture holder 2 as shown in FIG. 2D in a statewherein the fixture holder 2 is connected with the first intersectionalconnecting portion 51 a, the anchoring fixture holder 2′ interferes withthe first intersectional connecting portion 51 a, thereby serving toprevent the fixture holder 2 from being longitudinally separated fromthe first intersection connecting portion 51 a. Also, since the width ofthe entrance of the intersectional connecting portion 51 including thesecond intersectional connecting portion 51 b is larger than a diameterof the deformed steel wire 5, the deformed steel wire 5 can be fittedinto the intersectional connecting portion 51 through the entranceformed in a lateral direction of the intersectional connecting portion51.

In the above described intersectional connection type deformed steelwire 5′, the two intersectional connecting portions thereof have nochange in arrangement direction and plane even though the deformed steelwire 5′ is inverted. In other words, the two intersectional connectingportions of the intersectional connection type deformed steel wire 5′have no special distinction of upper and lower positions. Therefore, theterms “first” and “second” distinguishing the two intersectionalconnecting portions have no special meaning.

Referring to FIG. 9A, the beam connection loop type deformed steel wire5″ may be connected with two basic steel wires 5 such that the two steelwires 5 are horizontally arranged parallel to each other. To achieve thehorizontal parallel arrangement of the two deformed steel wires 5, alower one of the two deformed steel wires 5 may be penetrated throughthe beam connection loop 52 and the remaining upper deformed steel wire5 may be penetrated through the intersectional connecting portion 51.Similarly, as shown in FIG. 9B, the horizontal parallel arrangement ofthe two deformed steel wires 5 can be accomplished even by use of thebeam supporting type deformed steel wire 5′″. The beam connection looptype deformed steel wire 5″ may be modified such that an additionalintersectional connecting portion is formed at the upper side of theintersectional connecting portion 51, or may be longitudinallyconnected, at an upper end thereof, to the deformed steel wire 5′ by useof the fixture holder 2, for enabling the elements, used for thereinforcement of beam blocks, to be also used for the reinforcement of amasonry wall.

FIG. 10 is a front view illustrating a masonry wall, which is reinforcedby the fixtures 1, fixture holders 2, and deformed steel wires 5, 5′, 5″and 5′″ as described in FIGS. 8 and FIGS. 9A and 9B. FIG. 11A is asectional view taken along the line X-X of FIG. 10, FIG. 11B is asectional view taken along the line Y-Y of FIG. 10, and FIG. 11C is asectional view taken along the line Z-Z of FIG. 10.

FIG. 8 is related to a region designated by the line X-X of FIG. 10 andFIG. 11A. It can be confirmed from FIG. 8 that the fixture holder 2,which is coupled to the rear end of the fixture 1 embedded in the innerwall C, is connected perpendicular to the deformed steel wire 5′, whichextends in a vertical direction of the wall, via the firstintersectional connecting portion 51 a, and in turn, the deformed steelwire 5, which extends in a horizontal direction of the wall, is alsoconnected perpendicular to the vertically extending deformed steel wire5′ via the second intersectional connecting portion 51 b at the heightlower than the fixture holder 2 by the height of a single block. Each ofthe horizontally or vertically extending steel wires 5 and 5′ may belongitudinally connected to additional steel wire(s) by use of thefixture holder 2 as shown in FIG. 6A, for the sake of the reinforcementof the overall masonry wall.

FIG. 9A is related to a region designated by the line Y-Y of FIG. 10 andFIG. 11B. It can be appreciated from FIG. 9A that a first deformed steelwire 5, which extends horizontally by penetrating through a beam block9, and a second deformed steel wire 5, which is horizontally disposed onthe beam block 9 in the same direction as the first deformed steel wire5, are fitted into and fixed by the beam connection loop 52 and theintersectional connecting portion 51 of the beam connection loop typedeformed steel wire 5″, respectively, for the sake of supporting thebeam block 9. Also, it can be appreciated that the deformed steel wire5″ can be longitudinally connected to an additional deformed steel wire5″ by use of the fixture holder 2 as shown in FIG. 6A. In FIG. 11B, theintersectional connection type deformed steel wire 5′ is extended to anupper end of the beam connection loop type deformed steel wire 5″. Theintersectional connection type deformed steel wire 5′ is also used forthe reinforcement of a masonry wall.

FIG. 9B is related to a region designated by the line Z-Z of FIG. 10 andFIG. 1C. It can be appreciated from FIG. 9B that a first deformed steelwire 5, which extends horizontally by penetrating through the beam block9, and a second steel wire 5, which is horizontally disposed on the beamblock 9 in the same direction as the first deformed steel wire 5, arefitted into and fixed by the beam connection loop 52 and theintersectional connecting portion 51 of the beam supporting typedeformed steel wire 5′″, for the sake of supporting the beam block 9. Asshown in FIG. 10, the deformed steel wire 5′″ is effective to denselyconnect the deformed steel wire 5, which is horizontally penetratedthrough the beam block 9, and the deformed steel wire 5, which ishorizontally disposed on the beam block 9, to each other, therebyguaranteeing a more effective reinforcement of the beam block. Inparticular, by allowing the deformed steel wires 5 to be more denselyarranged in opposite end regions of the beam block 9, the deformed steelwire 5′″ having the above described configuration can surely and easilyeliminate the drooping of the ends of the beam block 9. Since thereinforcement of beam blocks requires an increased number of deformedsteel wires as compared to the number of deformed steel wires requiredfor the reinforcement of a masonry wall, the use of the beam connectionloop type deformed steel wires 5″ may cause an excessive consumption ofmaterials and an inconvenience in block laying. However, these problemscan be solved by the adoption of the beam supporting type deformed steelwire 5′″.

FIGS. 12A to 12C illustrate a block for use in the masonry wallreinforcing method of the present invention. The block 8 has a centerhole 81, a side surface groove 82, a first side hole 83, and a secondside hole 84. The side surface groove 82 is formed only at one outerside surface of the block 8, and all the above holes have a roundedrectangular shape. The reason why the groove is formed only at one sidesurface of the block is to prevent the groove of the block, which islocated at the corner of the wall (See the region L of FIG. 13), frombeing exposed to the outside. As compared to a circular hole, the abovedescribed rectangular hole has the effect of increasing the contact areaof upper and lower rows of blocks, thereby enabling a more strongconnection of the rows of blocks. In particular, the rectangular holehas the effect of not only providing an increased space required for thepenetration of the deformed steel wire, thus enabling an easy wirepenetrating operation, but also allowing the block to have a constantthickness around the hole, thus enabling a uniform firing of the blockwithout leaving a weak portion in the block and resulting in animprovement in both a rigidity and structural strength of the block.Moreover, since corners of the rectangular hole are rounded, it ispossible to prevent a stress from being concentrated at the corners, andconsequently, to reduce the potentiality of a breakage of the block tothe maximum extent.

With the masonry wall reinforcing method of the present invention, thelaying of blocks can be performed without a special restriction so longas neighboring blocks are arranged such that their side surface groovesface each other only at a location through which the verticallyextending deformed steel wire 5′ is penetrated (See the circle N of FIG.13). Therefore, there is no need for forming the side surface groove 82at both side surfaces of each block.

As shown in FIG. 12C, the center hole 81 of the block 8 has a roundedrectangular shape, which is substantially the same as a shape defined bytwo facing side surface grooves 82 spaced apart from each other by adistance M equal to the width of a masonry joint.

Comparing the sizes of the above mentioned holes with reference to FIG.12B, the center hole 81, which is perforated in the center of the block,has a width e smaller than a width h of the first and second side holes83 and 84. When blocks are alternately laid one above another, a mortarportion M between neighboring blocks is located above or below thecenter hole 81 of the underlying or overlying block. However, since themortar portion M has a lower strength than that of the block, in orderto reinforce the strength of the mortar portion M, it is necessary thatthe width e of the center hole 81 of the underlying or overlying blockmust be smaller than the width h of the first or second side hole 83 or84, such that a thickness g of the remained center portion of the blockaround the center hole 81 is larger than a width f of the remained sideportion of the block.

Also, the first side hole 83, located between the center hole 81 and theside surface groove 82, has a length c smaller than a length d of theopposite second side hole 84. This is to reduce a deviation between thethicknesses a and a′ of the block around the first side hole 83 and thethicknesses b and b′ of the block around the second side hole 84,thereby enabling a uniform firing of the block. If the length c of thefirst side hole 83 is equal to the length d of the opposite second sidehole 84, the deviation between the thicknesses a and a′ around the firstside hole 83 and the thicknesses b and b′ around the second side hole 84increases excessively, thus causing an irregularity in the firing of theblock and consequently, having a bad effect on the strength of theblock.

FIG. 13 illustrates the use of the above described block. It can beappreciated from FIG. 13 that the vertically extending deformed steelwire 5′ is penetrated alternately through the center hole 81 of theblock and the space defined by both the facing side surface grooves 82of the underlying neighboring blocks.

Although the beam block 9 shown in the lower part of FIGS. 11A to 11C orthe beam blocks shown in FIG. 13 are illustrated as though they havecircular holes, the block shown in FIG. 12 is also usable as the beamblock, and in particular, is more preferable in view of assisting ablock sorting operation of a mason.

Meanwhile, although FIGS. 12A to 12C and FIG. 13 illustrate the block 8having the side surface groove 82 formed only at one side surfacethereof, it will be appreciated that a block, having a pair of sidesurface grooves formed at both side surfaces thereof, can be used in theconstruction of a building except for the corners of the building.Providing the side surface grooves 82 at both side surfaces of the blockhas the effect of achieving a convenience in the laying of blocks.

Hereinafter, an embodiment of the masonry wall reinforcing method inaccordance with the present invention will be described with referenceto FIGS. 14A to 14E.

First, in a state wherein a first row of blocks 8 is laid around aperiphery of the inner wall C at a predetermined height as shown in FIG.14A, the deformed steel wire 5 is disposed in a peripheral direction ofa building (i.e. in a longitudinal direction of the blocks) as shown inFIG. 14B, and the deformed steel wire 5′ is penetrated through thecenter hole 81 of the block 8 in a height direction (i.e. verticaldirection) of the building. The deformed steel wire 5 is connected tothe deformed steel wire 5′ via the second intersectional connectingportion 51 b.

Next, as shown in FIG. 14C, after filling mortar in a masonry joint, asecond row of blocks is laid on the first row of blocks 8 such that sidesurface grooves 82 of two neighboring blocks face each other to define aspace for the penetration of the deformed steel wire 5′. Since the firstintersectional connecting portion 51 a of the deformed steel wire 5′ isspaced apart from the second intersectional connecting portion 51 b by adistance equal to the height of a single block, the first intersectionalconnecting portion 51 a is located at the height of an upper end surfaceof the second row of blocks. Also, since the first and secondintersectional connecting portions 51 a and 51 b are arrangedperpendicular to each other, the first intersectional connecting portion51 a is used for the connection of the fixture holder 2 that is orientedtoward the inner wall of the building. If the anchoring fixture holders2′ are fitted around the fixture holder 2 from opposite sides of thefixture holder 2 in a state wherein the fixture holder 2 is fitted intothe first intersectional connecting portion 51 a, the fixture holder 2longitudinally interferes with the inner periphery of the firstintersectional connecting portion 51 a, thereby being fixedly caught bythe first intersectional connecting portion 51 a.

Thereafter, a third row of blocks is laid on the second row of blocks asshown in FIG. 14D. By repeatedly performing the above describedprocedure as shown in FIGS. 14A to 14C, a plurality of deformed steelwires 5′ and 5 can be connected to one another in both the peripheraldirection and the vertical direction of the building, and furthermore, aplurality of fixture holders 2 can be connected thereto, for reinforcingthe strength of the resulting masonry wall.

Finally, if the fixture 1 is introduced into a rear end of each fixtureholder 2 until the fixture 1 is press-fitted into the inner wall whilebeing connected to the fixture holder 2, the overall masonry wall can bestrongly fixed to the inner wall.

Now, a beam block reinforcing method included in the above describedmasonry wall reinforcing method will be described with reference toFIGS. 15A to 15D.

First, a first deformed steel wire 5 is penetrated through a holeperforated in the beam block 9 as shown in FIG. 15A, and a seconddeformed steel wire 5 is disposed on an upper surface of the beam block9 as shown in FIG. 15B. Then, after inserting the lower first deformedsteel wire 5 into the beam connection loop 52 of the beam connectionloop type deformed steel wire 5″ as shown in FIG. 15C and inserting theupper second deformed steel wire 5 into the intersectional connectingportion 51 of the deformed steel wire 5″ spaced apart from the beamconnection loop 52 by a predetermined distance (equal to a distancebetween the two steel wires 5), mortar is filled in a masonry joint, andadditional rows of blocks are laid thereon. With this method, inaddition to surely supporting the beam block, the reinforcement of themasonry wall can be accomplished by repeatedly connecting additionaldeformed steel wires to an upper end of the beam connection loop typedeformed steel wire 5″ by use of the fixture holders 2 and also, byconnecting different kinds of deformed steel wires 5′ in a lateraldirection of the deformed steel wire 5 disposed on the upper surface ofthe beam block 9.

In particular, since the deformed steel wire 5, which is disposed on anupper surface of the last beam block (See the circle O of FIG. 13),protrudes toward the wall, the deformed steel wire 5 can support thebeam block with a strong force so long as the deformed steel wire 5 isnot cut.

FIG. 16 is an explanatory view illustrating a beam block reinforcingmethod applicable to an existing building. The sequence of the beamblock reinforcing method will now be described.

First, a row of beam blocks 9 and a plurality of rows of blocks (forexample, four rows of blocks) above the row of beam blocks 9 are removedtogether. Then, after supporting the remaining blocks, overlaid abovethe removed blocks, by use of temporary supports (not shown) so as toprevent the collapse of the blocks, as shown in FIGS. 15A to 15D, beamblocks 9 are disposed in a row such that their holes horizontallycommunicate with one another, such that a first deformed steel wire 5 ispenetrated through the communicating holes of the beam blocks 9. Then,blocks 8 are laid at the lateral side of the beam blocks 9, and a seconddeformed steel wire 5 is disposed on the upper surfaces of the blocks 8.Thereafter, the two deformed steel wires 5 are connected to the beamconnection loop 52 and the intersectional connecting portion 51 a of thedeformed steel wire 5″″.

Subsequently, after laying another row of blocks 8, the fixture holder 2is connected to the intersectional connecting portion 51 b of thedeformed steel wire 5″″.

After laying a further row of blocks 8, an additional deformed steelwire 5 is disposed in a horizontal direction of the building, so as tobe connected to the intersectional connecting portion 51 c of thedeformed steel wire 5″″.

After completing the laying of blocks 8 by filling mortar in a masonryjoint, the fixture 1 is press-fitted into the inner wall through thefixture holder 2 that is embedded in the masonry joint.

With the above described procedure, the reinforcement of beam blocks inthe existing building can be accomplished.
